2018 WRX. Protuned, 13000 miles. Mods are ( Cobb big SF Intake, Namless Turboback exhaust Catted. Every once in awhile mainly just cruising on the highway I will feel this buck! Like a jump or sudden loss of power for split seconds. It’s almost like a hiccup. Is this normal cruise knock I’m feeling, possible misfire? I show 0 knock and my dam is always at 1.0. I’ve been Protuned for 2 months now and I haven’t seen a single knock reading or dam drop. I was starting to wonder if he turned off the knock sensor but they said they didn’t. They are a very reputable tuner and everyone who went there also said they don’t play with the knock sensors. Maybe I have a faulty knock sensor from the factory? Maybe it’s not knock at all. Anyone know what I’m experiencing?
